This supports the things I have been saying.
The biggest threat to life is the next period of mass glaciation. It could take thousands of years, but we should already be in the cooling-down cycle. Even if we have a hundred years of warming, we have bigger environmental problems long term.
The Earth is halfway between its maximum tilt and its minimal tilt. We are 11,000 years away from the minimal tilt. All of human civilization arose during the last 11,000-year warm period.
The maximum tilt melts the glaciers because the summers are warmer. However, as the glaciers advance, a positive feedback cycle happens because the glaciers reflect more sunlight into space, rapidly cooling the planet.
It is possible that our effect on the climate could create a new normal. However, I don't see how we counter 90,000 years of cold before the next interglacial warm period.
